AI Construction Purchasing.
No More PO Chaos.
Managing POs, vendor bids, and budgets across 15+ active homes is chaos. Things fall through the cracks. You don't know where money is going until the home closes. Foreman AI changes that — in plain English.
The purchasing mess every builder knows
You don't know where POs stand
Bids come in via email, text, and phone. Nobody has a complete picture of what's been sent, received, or awarded.
Budget overruns surprise you
By the time you notice framing went 15% over, it's too late to react. The damage is already done.
Parts pricing is stale
Your parts catalog has prices from 18 months ago. You're estimating based on old data and eating the difference.
Vendor performance is guesswork
You know which subs you prefer — but you can't actually tell your PM who responds to bids and who ghosts them.
Plain English. Real results.
This is what Foreman AI can do with your actual purchasing data right now.

Everything purchasing covers
Not a generic PO tool. Purpose-built for residential home builders managing multiple communities.

Search, create, bulk import, and update parts. Web scraping plus direct supplier API connections pull live pricing, product images, and model numbers from major distributors. No stale spreadsheets — real MSRPs, auto-linked to your design center.
Vendor Management
Full vendor directory with performance scorecards. Bid response rates, win rates, insurance tracking, and contact history — all in one place.
Bid Management
Draft bid requests, send portal invites, compare normalized bids, and generate bid comparison reports. Foreman ranks vendors and recommends best value.
Budget Tracking
Real-time budget vs. actual across all homes. Variance flags, scope-level breakdowns, and profitability reports by community — generated in plain English.
PO Generation
Generate professional purchase orders and Scope of Work documents from your real project data. Excel exports with company branding, ready to sign.
Bid Import AI
Upload vendor bids in ANY format — Excel, PDF, scanned docs, photos of handwritten quotes. AI extracts line items, fuzzy-matches to your parts catalog with confidence scores, and lets you review each item before importing as a Bid, Vendor Pricing, or Takeoffs.
PO generation, on YOUR terms.
Most construction software hard-codes one PO model. Cornerstone gives you four ways to generate purchase orders — mix and match per scope, per community, per task. Your cash flow rules drive the system, not the other way around.
Generate every PO across the entire build the moment the home is approved. Vendors get full visibility, accounting locks in budget exposure on day one. Best for established builder-vendor relationships.
Need to pay a deposit at permit pull or contract signing? Generate a partial deposit PO from any earlier pipeline task, before the work is done — then top it up later.
When a construction task is marked complete, Cornerstone auto-generates a full PO for that scope and vendor — no manual step required. Cash goes out only when work is verifiably done.
Turn PO generation on or off for specific tasks, scopes, or communities. Mix all three patterns above on the same job. You control the rules.
Supplier catalogs, inside your AI.
Cornerstone PM is building the first construction management platform where your AI assistant has direct access to supplier catalogs. Foreman connects to supplier APIs to pull real-time product data, live pricing, and official product images — straight into your parts catalog and design center.
Ask Foreman for products by name, budget, finish, or brand. Get actual results from supplier catalogs with current MSRPs.
No more estimating from 18-month-old spreadsheets. Supplier API pricing flows directly into your budgets and design center.
Set up entire fixture packages across all floorplans in minutes — real images, MSRPs, and model numbers from suppliers.
Compare the same product across multiple suppliers. Track pricing changes over time. Make data-driven purchasing decisions.
Cornerstone isn't just software you use.
It's a platform your AI agents act on.
Pro+ exposes a full REST API so any AI agent — custom-built, voice-based, or email-scanning — can read and write your Cornerstone data. The optionality is unlimited.
Your voice agent calls a roofing company, gets their contact info, and Cornerstone adds them as a vendor automatically. Zero manual entry.
An email agent reads incoming vendor emails, extracts bid data, and logs it in Cornerstone — no one touches the keyboard.
Voice agent calls your vendor list, explains the scope, and directs them to your bid portal. 200+ vendors contacted in an afternoon.
Agent monitors task completions and triggers PO generation automatically — the schedule drives purchasing without you in the loop.
Agent calls the framer who hasn't confirmed their schedule date. Records the outcome. Updates the task status.
Claude, GPT-4, LangChain, custom-built — if it can make an HTTP request, it can act on your Cornerstone data.
